[Bug 1724650] Re: [Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version: 0x25 (or later)

[Dan Streetman]

> There is a proposed upstream patch: lp:1726303

that bug is dup of bug 1724912

but, the patch will only "help" you if the TSC_DEADLINE disabling was
done incorrectly, i.e. if your system doesn't actually have that timer.
That isn't the case for you.

Because pre-artful 4.13 the kernel doesn't have the commit that actually
checks the ucode and disables the timer for buggy fw versions.  (I
should probably get that commit backported to avoid buggy TSC_DEADLINE
timer use).

If your cpu ucode isn't at the fixed level, your TSC_DEADLINE timer is
buggy and may cause problems.

As @chiluk said, you need to install intel-microcode and reboot; that
will get your cpu up to the correct fixed level of ucode.
